I have no sympathy whatsoever for Glitch. She could have made different choices after escaping from the facility she was locked up at, than to go after Dynagirl. Once she made that choice, it was inevitable that she’d come to an end much like this.

You’re right of course, Stacy did not go after Kerri. But Kerri didn’t go after Stacy either, she just ended up on the same island, and Stacy seems to have interpreted the (admittedly uncanny) coincidence as an attack and responded accordingly.

And now that interpretation of events had led Stacy to the unfortunate position she finds herself in. Though I’m beginning to see it as unlikely that Kerri will kill her, she’s already had plenty of opportunity to do so and Stacy is clearly outmatched.
